Question

find the domain y=14x-2

Answer 1

Domain is all allowed values of x.
Is there any restriction that we need to place on the x-value in the equation y = 14x - 2?

Answer 2

Here, no x-value will cause problems such as division by zero or taking the square root of a negative number, etc. So there is NO restriction on the x values. So the domain is ALL real numbers. In interval notation, the domain is: (-infinity, infinity).
